Thanks Colleen. I find that my symptoms are cyclical. Always taking famotidine. Adding dexalant when burning in throat gets particularly bad. I’ve stopped all the herbal supplements - didn’t seem to make a difference one way or the other. I eat to keep things under control - no alcohol, citrus, tomato sauce, spicy foods, etc. helps get things under control. I can then add a few things on occasion and follow up with Gaviscon without ill effect. I didn’t want to hear this when my symptoms all began, but it takes a long time to figure out what works for you. All the tests I underwent came back “good” - so it was up to me to work through. Lots of good suggestions on this site. Try not to get discouraged.
